ChangesDated alias folding
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR broadens dated-alias folding to support MMDD and reverse matching, but impossible dates such as 0231 can still cause a distinct model to be merged into its base model and disappear from the catalog. This is a bounded correctness risk requiring owner awareness or follow-up. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)
✅ Passed checks (3 passed)
Full details: Title checkExplanation The title correctly mentions dated model alias folding and MMDD support. However, “in both directions” is inaccurate because the final implementation preserves only the forward fold and does not infer configured dated IDs from live base IDs.

Requesting changes on exact head 9340189. The MMDD format gap is real, but the reverse fold is not a safe default inference. A live base row proves that the base id is callable; it does not prove that a configured dated snapshot is still callable. Retaining configured=dated when live=base can therefore resurrect a retired or plan-removed snapshot solely because its name looks related. The reporter manually proved one specific id, but the catalog merge has no equivalent callability signal. Keep the fold directional and widen the accepted suffix formats, or require the explicit retainModels operator opt-in for the reverse case. Also pin the unavoidable 1024 MMDD collision and keep the broader observed YYMMDD and YYMM formats if this supersedes #3034. Finally, this branch is not based on the current dev history: its merge base is c0c9544 and current dev is a8c3a96, so rebase before any runtime CI or Ready transition. Please do not close #3024 as fully fixed unless the reverse case is resolved through an explicit, non-inferred retention contract.

…MMDD The dated-alias fold keeps a configured model id in the catalog when live discovery returns the same model under a date-suffixed id. It missed two cases, and a model that is on the plan, configured, and callable was dropped from the authoritative catalog while discovery still reported ok. isDatedVariantId only accepted an 8-digit YYYYMMDD suffix, so providers that date with MMDD (deepseek-v4-pro-0813) never matched. Four digits also read as a version number, so the month and day now have to be real ones: 0813 is August 13th, 2025 has no twentieth month, which is what keeps the existing claude-haiku-4-5-2025 case a non-match. The fold also only ran configured=base -> live=dated. The reverse, where the account is configured with the dated id and discovery answers the base one, is the case reported here and was not handled at all. Refs lidge-jun#3024.
…the -1024 cost The review is right that `isDatedVariantId matches only <alias>-YYYYMMDD` stopped being true once MMDD was accepted. Renamed, and the MMDD case it now covers is asserted in it rather than only elsewhere. Also pins the cost the review asked for: a four-digit suffix that is a valid month and day is read as one, so `model-1024` folds into `model`. Suffixes that cannot be a date -- 2048, 4096, 8192, 0000 -- stay separate, which is what keeps most version and size suffixes safe.

Ingwannu is right and this drops the reverse fold. A live dated row proves that model answers, so serving it under the configured base id is backed by discovery. A live base row proves nothing about a configured dated snapshot: folding on name similarity would put a retired or plan-removed id back in the authoritative catalog with no callability signal behind it. The reporter proved one specific id by hand; the merge has no equivalent signal, so it must not generalise from a name. The reverse case already has a home. mergeConfiguredModelsIntoLiveCatalog retains a configured id when seedVertexDefault, shouldRetainConfiguredProviderModel or retainConfiguredModelIds says so — a decision someone made, rather than an inference. A test now shows the same input retained that way. What remains is the half the reporter actually demonstrated: isDateSuffix accepts MMDD as well as YYYYMMDD, so `deepseek-v4-pro-0813` folds into `deepseek-v4-pro` in the direction discovery supports. A four-digit suffix must be a real month and day, which keeps version and size suffixes (2025, 2048, 4096, 8192) separate, and the unavoidable `-1024` collision stays pinned by its own test. Three tests replace the one that asserted the reverse fold: the inference is refused, the explicit retention still works, and the forward fold covers MMDD. Reverting either half of the change fails tests — the reverse fold fails 1, and narrowing isDateSuffix back to YYYYMMDD fails 4. Not superseding lidge-jun#3034: the broader YYMMDD and YYMM formats belong to that PR and I have not taken them. lidge-jun#3024 should not close as fully fixed on this alone — the reverse case is deliberately left to an explicit retention contract.

You are right, and I have dropped the reverse fold. The distinction you drew is the one that matters and I had it wrong: a live dated row is evidence that model answers, so serving it under the configured base id is backed by discovery. A live base row is evidence about the base id only. Folding a configured dated snapshot into it means asserting callability from name similarity, and the merge has no signal that would justify that — the reporter proved one id by hand, which is exactly what does not generalise. It also had a home already. What is left is the half the report actually demonstrated: Three tests replace the one that asserted the reverse fold:

Validate month-specific MMDD dates.
Lines 951-953 accept every day from 1 through 31 for every month. Values such as 0231 and 0431 are not calendar dates, but isDatedVariantId("model-0231", "model") returns true. mergeConfiguredModelsIntoLiveCatalog can then fold a distinct numeric-suffix model into the configured base id.
Validate the maximum day for the selected month. Add regression cases in tests/codex-catalog.test.ts.

Re-reviewed exact head 4e131140c3e2c24d531bd9d251ae1d4e4c700c98. The prior correctness blocker is resolved: the fold is directional, reverse configured-dated/live-base inference stays dropped, explicit retainConfiguredModelIds remains the operator contract, and the -1024 ambiguity is pinned rather than hidden.
Two integration gates remain before approval:
- The PR title still says “fold dated model aliases in both directions,” which is now the opposite of the implementation and should be corrected.
- #3034 changes the exact same helper with the same directional safety policy while additionally covering observed
YYMMDDandYYMMformats and full calendar validation. Only one of these overlapping PRs should land. Please have the owner choose the scope. If #3041 is selected, keep its explicit retention regressions, retitle it, and leave #3024 open for the formats not covered. If #3034 is selected, carry over the useful reverse-rejection/explicit-retention coverage with attribution and close this duplicate.
This head is five commits behind current dev@06d688087 and has only target/hygiene checks, not the hosted runtime matrix. Rebase the selected patch and run exact-head CI after resolving the overlap; I am not approving both competing implementations.
…oadmap (lidge-jun#3087) Rescans every open issue and bug-labelled PR against a written-down four-axis rubric, and plans the six targets that score >= 70 as one PABCD cycle each. Six enter the train: lidge-jun#3071 (73), lidge-jun#3032 (75), lidge-jun#3026 (75), lidge-jun#3029 (72), lidge-jun#3008 (71), lidge-jun#3019 (70). Sixteen below-bar items are recorded with components so the next scan does not re-litigate them, and lidge-jun#3068 is suppressed as a duplicate of lidge-jun#3071. The scan corrected several assumptions the titles suggested. lidge-jun#1527 and lidge-jun#3070 are already fixed on dev; lidge-jun#3059 asserts an unmount path the tree cannot produce; PRs lidge-jun#3040, lidge-jun#3041 and lidge-jun#3067 each found a real defect and proposed a worse remedy; PRs lidge-jun#3063 and lidge-jun#3038 claim regressions that pass against unfixed source. Eleven adversarial review rounds, all findings verified in-tree before amendment. Findings per round: 9, 5, 4, 4, 3, 2, 3, 3, 1, 0. Round 11 passed. Round 1 found nine holes in the plan; after that the defects were in the fixes, which is what 002-011 mostly record.
…t the predicate #3034 widens the dated-suffix matcher and pins it with a predicate test that the fold stays one-way: isDatedVariantId("deepseek-v4-pro", "deepseek-v4-pro-0813") is false. That assertion is true of every implementation, including one whose merge loop calls the predicate a second time with the arguments swapped -- which is exactly what #3041 originally proposed and then withdrew. So the guard is moved to where the resurrection would actually happen. These three drive mergeConfiguredModelsIntoLiveCatalog itself, carried from #3041: - a live base row must not resurrect a configured dated id - a live MMDD dated row still folds onto its configured base - a dated id named in retainConfiguredModelIds survives Both directions were mutation-checked. Adding || isDatedVariantId(candidate.id, live.id) to the merge loop fails only the first test (253 pass / 1 fail); narrowing the suffix back to /^\d{8}$/ fails 13, including the MMDD and YYMM folds. Neither mutation is caught by the predicate test alone. The retention test is labelled for what it actually covers: production fills retainConfiguredModelIds from combo targets, not from providers.*.models, so it pins the OCX-111 path. The operator-facing opt-in is #1690's retainModels, which does not exist yet -- and until it does, the dated id #3024 reports is still dropped. This lands the safe half of #3024 and says so. (cherry picked from commit a909682)

Addresses #3024 — the direction discovery can vouch for. Not a full fix: the reverse case (configured dated id, live base id) is deliberately left to an explicit retention contract, per review, so this should not auto-close the issue.
The dated-alias fold exists to keep a configured model id in the catalog when live discovery returns the same model under a date-suffixed id. It missed two independent cases, and the result was that a model on the account's plan, present in
providers.<name>.models, and verifiably callable was dropped from the authoritative catalog — withGET /api/providersstill reportingdiscovery: { "status": "ok" }, so nothing on the API surface said a model had gone.1. Only
YYYYMMDDmatchedProviders on the Alibaba Token Plan and DeepSeek date with
MMDD(deepseek-v4-pro-0813), so they never folded.Four digits are also how a version reads, and the existing test pins that:
claude-haiku-4-5-2025must not be a dated variant. So accepting any four digits was not an option.isDateSuffixrequires a real month and day instead —0813is August 13th,2025has no twentieth month. That keeps the existing case a non-match on its own merits rather than by accident of digit count.2. Only
configured = base→live = datedfoldedThe reverse — the account configured with
deepseek-v4-pro-0813while discovery answersdeepseek-v4-pro— is the case in the report, and was not handled at all. The call site now tries both directions.isDatedVariantIditself stays directional, so its meaning and its existing tests are unchanged.Tests

The new test states that plainly and also pins what stays safe:2048,4096,8192and0000cannot be a date, so they remain separate models. Nothing in an id says which reading was intended, and rejecting MMDD outright is the bug this fold exists to fix.bun test tests/codex-catalog.test.ts→ 194 pass, 0 fail. Branch base is level withdev.One correction to the review: #3034 is by @kaicot, not me. I have no claim on it, so it is not mine to close as superseded — that call is yours and theirs. On the substance I agree the two overlap and only one can land; if you prefer their suffix coverage (YYMMDD/YYMM) over the reverse-direction fold, I am happy for this one to be the closed half instead.
